description

A CupLock Ledger is a horizontal scaffold component designed to span between two CupLock standards (vertical posts) in the CupLock scaffolding system. It connects the vertical and horizontal members of the scaffold and helps create a stable structure for supporting scaffolding platforms. The HDG (Hot-Dip Galvanized) finish provides the ledger with superior corrosion resistance, ensuring that the ledger remains durable even in challenging environments exposed to moisture, chemicals, and extreme weather conditions.

key features

The CupLock Ledger (HDG) is designed with several important features that enhance its functionality and safety:

• Material: Made of steel, the CupLock ledger is treated with the Hot-Dip Galvanization (HDG) process, which coats the steel with a thick layer of zinc. This offers protection from rust and corrosion, especially in outdoor environments.
• Shape and Design: The ledger typically has an I-beam or rectangular shape, and it is designed to lock into the CupLock coupling system. The connection points on the ledger allow it to fit securely into the vertical scaffold standards, creating a stable grid structure.
• Corrosion Resistance: The HDG coating ensures that the ledger can withstand prolonged exposure to outdoor conditions without rusting or degrading, extending its service life compared to non-galvanized components.
• Load-Bearing Capacity: The CupLock Ledger is designed to support significant loads, depending on the project requirements. The specific load-bearing capacity will vary depending on the ledger’s dimensions and material strength, but it must comply with standards like BS 1139 and EN 12811-1.
• Ease of Assembly: The CupLock Ledger (HDG) fits securely into the CupLock couplers (top and bottom cups) that connect it to the vertical standards, creating a solid and stable connection. This tool-free assembly method makes it quick and efficient to install and remove.

uses

The CupLock Ledger (HDG) is an ideal solution for a variety of tasks that require reaching elevated spaces. Key uses include:

• Providing Horizontal Support: The primary function of the CupLock Ledger is to provide horizontal support for the scaffold platform. It serves as the foundation for placing scaffold boards, decking, or other working platforms, ensuring stability and load distribution across the scaffold system.
• Enhancing Scaffold Stability: By connecting the vertical standards and horizontal ledgers, the CupLock Ledger helps maintain the structural integrity of the scaffolding. It supports the vertical load of the scaffold and ensures that the entire scaffolding system remains stable during use.
• Long-Term Use in Harsh Conditions: Due to its Hot-Dip Galvanized (HDG) coating, the CupLock Ledger is well-suited for long-term use in environments with high moisture, chemicals, or weather extremes. It's particularly effective for projects exposed to the elements, such as construction, maintenance, and industrial scaffolding.
• Building Tall Scaffolds: The CupLock Ledger is integral to multi-level scaffolding systems, providing horizontal connections across various levels to ensure safe and accessible working platforms. Its ability to withstand heavy loads makes it ideal for high-rise projects or work at significant heights.
• Temporary Scaffolding Systems: The HDG-coated CupLock Ledger is often used in temporary scaffolding systems in construction or industrial settings where both safety and durability are required. It ensures that the scaffold is secure while workers are at height.

standards

The CupLock Ledger must comply with several international standards to ensure that it meets safety, strength, and performance criteria.

• BS 1139 (British Standard): Ensures that the CupLock Ledger, including the HDG finish, meets required strength and load-bearing capacity.
• EN 12811-1 (European Standard): Specifies the performance requirements for temporary scaffolding systems, ensuring that the CupLock Ledger (HDG) is safe for use, meets strength requirements, and provides stable and secure support.
• EN 74 (European Standard): Ensures that all components, including the CupLock Ledger, are properly secured when connected to the scaffold standards. The standard helps ensure the integrity of the CupLock system connections and guarantees they will not loosen during use.
• OSHA Regulations (USA): Ensures that the CupLock Ledger (HDG) meets safety standards for scaffolding in the United States, including requirements for load capacity, structural integrity, and worker safety.
• ANSI A10.8 (American National Standards Institute): Provides guidelines for scaffolding safety in the U.S., including requirements for scaffolding components like the CupLock Ledger. The HDG coating is expected to meet ANSI’s corrosion resistance standards to ensure long-term durability.
• ISO 9001 (Quality Management System): Ensures that the manufacturing process for the CupLock Ledger complies with international quality standards. Manufacturers must follow strict quality control procedures to ensure that the ledgers meet performance and safety specifications, especially for HDG-coated components.
• Hot-Dip Galvanization Standard: The HDG coating must meet the ISO 1461 standard, which provides specifications for the hot-dip galvanization process, ensuring that the zinc coating is applied uniformly and provides effective corrosion protection to the CupLock Ledger.

conclusion

The CupLock Ledger (HDG) is an essential part of the CupLock scaffolding system, providing vital horizontal support for scaffolding platforms and ensuring the structural integrity of the scaffold. The Hot-Dip Galvanized finish makes it highly resistant to corrosion and ideal for long-term outdoor projects or construction sites exposed to harsh environmental conditions. By adhering to international standards such as BS 1139, EN 12811-1, and OSHA regulations, the CupLock Ledger (HDG) guarantees safety, strength, and performance for scaffolding systems in various construction and industrial applications.
